SCREWLESS RAIL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 674,019, dated May 14, 1901. Application filed January 9, 1901. Serial No. 42,612. (No model.)

To all whom it may concern:

Be it known that I, FRANZ SOHEINIG, manager of electric works, a subject of the Emperor of Austria-Hungary, residing at 4 Museumstrasse, Lintz-Urfahr, Austria-Hungary, have invented certain new and useful Improvements Relating to Screwless Rail-Couplings, of which the following is a specification.

The object of the present invention is a screwless rail-coupling which can be employedtwo clamps surrounding the rail-foot of two adjacent rails, which clamps are pressed upon the rail-foot by means of a wedge driven in between them. Two forms of construction of a rail-coupling of this kind are illustrated in the accompanying drawings, in which Figure 1 is a side view of the one form of construction. Fig. 2 shows the same in section applied to a tramway-rail, by way of example. Fig. 3 illustrates in section the second constructional form applied, by way of example, to a railway-rail.

As will be seen from the drawings, the coupling of two adjacent rails 1 and 2 is effected by the two clamps 3 4, each of which respectively grasps the rail-foot on one side. The clamp 3 extends to the near side of the rail-foot and there forms an abutment 6 for the securing-wedge 7, driven in between it and the clamp 4.

When setting up the railcoupling, the clamp4is first placed on the rail-foot and then the clamp 3 (the latter in a red-hot condition) in such a manner that the junction of the two rails is in the center of the length of the clamp. The wedge 7 is now driven in sidewisethat is, parallel to the railand its thin projecting end bent round to secure the wedge.

The wedge shown in the drawings is tapered according to its width or section, Figs.

2 and 3, and is arranged so that the thin end of the wedge is at the top and the thick end at the bottom. By means of this shaped wedge the bar 3 is securely attached to the bar 4, as the wedge 7 has a tendency to force the abutment 6 upward. The angle a is preferably ateighty-five degrees and the angle [3 at eighty degrees. As the angle 01 is under ninety degrees the wedge 7 holds the bar 3 more securely. Owing to the form and arrangement of the wedge 7 it is impossible for the coupling to shake loose when a train passes over. If fish-plates 8 9 are employed in this coupling, the ends 10, which cover the rail-foot, are notched at 11 to the width of the bars 3 4.

In the form of construction illustrated in Fig. 3 the rail-coupling for railway-rails is assumed to be a simple fish-plate coupling without a foot, and therefore no notches are necessary on the fish-plates 8 9. It is necessary, however, in this rail-coupling to secure the clamps 3 4 against longitudinal displacement, which may result from the expansion or contraction of the rails. This is easily effected by expanding the rail-foot at both sides of the bars 3 4 at the edge by means of a chisel or by providing the ordinary fishplates at both sides with projections.

Having now particularly described and ascertained the nature of my invention, I declare that what I claim is- The combination, with the rail, of a pair of clamps receiving the foot of said rail and one of them having a substantially vertical abutment between which and said foot of the rail the other clamp is disposed, and a wedge interposed between said abutment and said lastnamed clamp and having those of its faces adjacent said abutment and clamp inclined downwardly away from the rail,the outer of these faces being inclined to a greater degree than the inner, and the abutment or clamp having faces corresponding to those of the wedge, substantially asdescribed.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
